Abstract (en)

A heat exchanger is provided. The heat exchanger includes a bundle of elongated tubes having open ends for a first fluid, a pair of manifolds and a housing. The pair of manifolds located on both sides of the open ends of the elongated tubes. The housing is configured to form a conduit for the second fluid and at least partially encapsulating the elongated tubes. The housing includes an inner surface facing the elongated tubes and at least one connection point formed by two perpendicular portions of the housing. Further, one of the perpendicular portions has a bent section forming the connection point by parallel arrangement with the other portion. The heat exchanger further includes at least one sealing portion located at least within the housing, so that the sealing portion overlaps at least portion of the connection point adjacent to at least one manifold.
